Supporting waste minimization studies by integrating expert system with process simulators

Volume: 21
Issue: C
Pages: 1003 - 1007
Waste minimization of large-scale chemical processes poses a multi-dimensional challenge. In this paper, we present an integrated solution framework consisting of an expert system and process simulator. The proposed framework has been developed by capitalizing on the CAPE-OPEN capability of HYSYS simulator through XML data exchange. First, a qualitative analysis is carried out by the expert system to diagnose the sources of wastes and to derive heuristics solutions. This is followed by quantitative assessment at process variable level using HYSYS modelling engine. Stochastic optimization of process variables for minimizing waste and maximising product flow is also performed. We illustrate the framework using an ammonia synthesis case study. © 2006 Elsevier B.V. All rights reserved.
